Packet Sniffing

Packet Sniffing is the process of monitoring and capturing data packets traveling across a network. In the context of trading, it can be used to analyze the flow of market data or to detect the strategies of competitors by observing their order patterns.

While legitimate for network troubleshooting and security monitoring, it can also be used maliciously to gain unauthorized insights into trade flows. Advanced traders might use this to understand how different participants are interacting with the exchange.

Protecting against unauthorized sniffing is a critical component of cybersecurity for trading firms. It involves encryption and secure protocols to ensure that sensitive order information remains private and cannot be intercepted by adversarial entities.
